Hi Marianne,

Thanks for incorporating Ben's feedback. I have some suggested wording 
improvements on the latest changes.

Section 1.1, p 1 -

Current:

                                                         A session
    case is an information indicating the status of the session in
    which the served user is involved (originating, terminating..).

Suggested:

                                                        A session
    case is metadata that captures the status of the session of a
    served user: whether the served user is registered or not, and
    whether the session originates or terminates with the served
    user.

Section 1.3, p 1 -

Current:
	                                                  A filter
    criteria is a user profile information that determines whether a
    particular initial request needs to be sent to a particular AS.

Suggested:

    Filter criteria is information in the user profile that
    determines whether an initial request is sent to a
    particular AS.

Section 5, bullet 2 -

Current:

    o  In [RFC5502], except for security reasons, it is not to clearly
       stated what to do with the received P-Served-User header field
       when a call is diverted to another destination.  This document
       dealing with this specific use case, highlights that several
       possibilities exist: the S-CSCF could store the previous
       "regstate" value and decide that the same value applies, or the
       "regstate" may not be relevant after a diverting service and
       removed, or the regstate could be combined with the orig-cdiv
       session case to provide different services if the served user is
       registered or unregistered.  These choices are implementation
       dependent.

Suggested:

    o  [RFC5502] does not clearly state what to do with the received
       P-Served-User header field when a call is diverted to another
       destination. This document highlights that there are several
       ways of handling the P-Served-User header field: the S-CSCF could
       store the previous "regstate" value and decide that the same value
       applies; or the "regstate" may no longer be relevant after a
       diverting service so the S-CSCF removes it; or the regstate could
       be combined with the orig-cdiv session case to provide different
       services depending on whether the served user is registered or
       unregistered. These choices are implementation dependent.

Thanks!

Jean
